Method and apparatus for inducing the permeation of medication into internal tissue

ABSTRACT

An apparatus is described for selectively inducing the permeation of a liquid to a region of a stenosis in a blood vessel in a patient&#39;s body. The apparatus includes an external electrode (13) for positioning outside the patient&#39;s body and a catheter (10) carrying an internal electrode (38) for positioning adjacent a stenosis in a blood vessel in the body. The apparatus includes means for inducing an electric field between the internal electrode (38) and the external electrode (13) which is pulsed in phase with the patient&#39;s cardiac rhythm. &lt;IMAGE&gt;
